Vaginitis

Overview

Vaginitis is an inflammation of the vagina that can result in discharge, itching and pain. The cause is usually a change in the normal balance of vaginal bacteria or an infection. Reduced estrogen levels after menopause and some skin disorders can also cause vaginitis.

The most common types of vaginitis are:

Bacterial vaginosis, which results from a change of the normal bacteria found in your vagina to overgrowth of other organisms

Yeast infections, which are usually caused by a naturally occurring fungus called Candida albicans

Trichomoniasis, which is caused by a parasite and is commonly transmitted by sexual intercourse

Treatment depends on the type of vaginitis you have.

Symptoms

Vaginitis signs and symptoms can include:

Change in color, odor or amount of discharge from your vagina

Vaginal itching or irritation

Pain during intercourse

Painful urination

Light vaginal bleeding or spotting

If you have vaginal discharge, which many women don't, the characteristics of the discharge might indicate the type of vaginitis you have. Examples include:

Bacterial vaginosis. You might develop a grayish-white, foul-smelling discharge. The odor, often described as a fishy odor, might be more obvious after sexual intercourse.

Yeast infection. The main symptom is itching, but you might have a white, thick discharge that resembles cottage cheese.

Trichomoniasis. An infection called trichomoniasis (trik-o-moe-NIE-uh-sis) can cause a greenish-yellow, sometimes frothy discharge.

When to see a doctor

You have a particularly unpleasant vaginal odor, discharge or itching.

You've never had a vaginal infection. Seeing your doctor can establish the cause and help you learn to identify the signs and symptoms.

You've had vaginal infections before.

You've had multiple sex partners or a recent new partner. You could have a sexually transmitted infection. Some sexually transmitted infections have signs and symptoms similar to those of a yeast infection or bacterial vaginosis.

Wait-and-see approach

You probably don't need to see your doctor every time you have vaginal irritation and discharge, particularly if:

You've previously had a diagnosis of vaginal yeast infection and your signs and symptoms are the same as before

You know the signs and symptoms of a yeast infection, and you're confident that's what you have

Causes

The cause depends on what type of vaginitis you have:

Bacterial vaginosis. This most common cause of vaginitis results from a change of the normal bacteria found in your vagina, to overgrowth of one of several other organisms. Usually, bacteria normally found in the vagina (lactobacilli) are outnumbered by other bacteria (anaerobes) in your vagina. If anaerobic bacteria become too numerous, they upset the balance, causing bacterial vaginosis.

This type of vaginitis seems to be linked to sexual intercourse — especially if you have multiple sex partners or a new sex partner — but it also occurs in women who aren't sexually active.

Yeast infections. These occur when there's an overgrowth of a fungal organism — usually C. albicans — in your vagina. C. albicans also causes infections in other moist areas of your body, such as in your mouth (thrush), skin folds and nail beds. The fungus can also cause diaper rash.

Trichomoniasis. This common sexually transmitted infection is caused by a microscopic, one-celled parasite called Trichomonas vaginalis. This organism spreads during sexual intercourse with someone who has the infection.

In men, the organism usually infects the urinary tract, but often it causes no symptoms. In women, trichomoniasis typically infects the vagina, and might cause symptoms. It also increases a women's risk of getting other sexually transmitted infections.

Noninfectious vaginitis. Vaginal sprays, douches, perfumed soaps, scented detergents and spermicidal products may cause an allergic reaction or irritate vulvar and vaginal tissues. Foreign objects, such as tissue paper or forgotten tampons, in the vagina can also irritate vaginal tissues.

Risk factors

Hormonal changes, such as those associated with pregnancy, birth control pills or menopause

Sexual activity

Having a sexually transmitted infection

Medications, such as antibiotics and steroids

Use of spermicides for birth control

Uncontrolled diabetes

Use of hygiene products such as bubble bath, vaginal spray or vaginal deodorant

Douching

Wearing damp or tightfitting clothing

Using an intrauterine device (IUD) for birth control

Complications

Women with trichomoniasis or bacterial vaginosis are at a greater risk of acquiring sexually transmitted infections because of the inflammation caused by these disorders. In pregnant women, symptomatic bacterial vaginosis and trichomoniasis have been associated with premature deliveries and low birth weight babies.

Prevention

Good hygiene may prevent some types of vaginitis from recurring and may relieve some symptoms:

Avoid baths, hot tubs and whirlpool spas.

Avoid irritants. These include scented tampons, pads, douches and scented soaps. Rinse soap from your outer genital area after a shower, and dry the area well to prevent irritation. Don't use harsh soaps, such as those with deodorant or antibacterial action, or bubble bath.

Wipe from front to back after using the toilet. Doing so avoids spreading fecal bacteria to your vagina.

Treatment

A variety of organisms and conditions can cause vaginitis, so treatment targets the specific cause:

Bacterial vaginosis. For this type of vaginitis, your doctor may prescribe metronidazole (Flagyl) tablets that you take by mouth or metronidazole (MetroGel) gel or clindamycin (Cleocin) cream that you apply to your vagina. You'll need to get tested and be given a prescription for these medications.

Yeast infections. Yeast infections usually are treated with an over-the-counter antifungal cream or suppository, such as miconazole (Monistat 1), clotrimazole (Gyne-Lotrimin), butoconazole (Femstat 3) or tioconazole (Vagistat-1). Yeast infections may also be treated with a prescription oral antifungal medication, such as fluconazole (Diflucan). The advantages of over-the-counter treatment are convenience, cost and not waiting to see your doctor. However, you might have something other than a yeast infection. Using the wrong medicine may delay an accurate diagnosis and proper treatment.

Genitourinary syndrome of menopause (vaginal atrophy). Estrogen — in the form of vaginal creams, tablets or rings — can effectively treat this condition. This treatment is available by prescription from your doctor, after other risk factors and possible complications are reviewed.

Noninfectious vaginitis. To treat this type of vaginitis, you need to pinpoint the source of the irritation and avoid it. Possible sources include new soap, laundry detergent, sanitary napkins or tampons.

Lifestyle and home remedies

You'll need prescription medication to treat trichomoniasis, bacterial vaginosis and vaginal atrophy. If you know you have a yeast infection, you can take these steps:

Use an over-the-counter medication specifically for yeast infections. Options include one-day, three-day or seven-day courses of cream or vaginal suppositories. The active ingredient varies, depending on the product: clotrimazole (Gyne-Lotrimin), miconazole (Monistat 1) or tioconazole (Vagistat-1).

Some products also come with an external cream to apply to the labia and opening of the vagina. Follow package directions and complete the entire course of treatment, even if you're feeling better right away.

Apply a cold compress, such as a washcloth, to the labial area to ease discomfort until the antifungal medication takes full effect.

Preparing for an appointment

Your family doctor, gynecologist or another medical practitioner can diagnose and prescribe treatment for vaginitis.

What you can do

To get ready for your appointment, make a list of:

Your symptoms and how long you've had them

Key personal information, including how many sex partners you have and whether you have a new sex partner

All medications, vitamins and other supplements you take, including doses

Questions to ask your doctor

Avoid using tampons, having sexual intercourse or douching before your appointment so that your doctor can assess your vaginal discharge.

For vaginitis, some basic questions include:

What can I do to prevent vaginitis?

What signs and symptoms should I watch for?

Do I need medication?

Are there over-the-counter products that will treat my condition?

What can I do if my symptoms return after treatment?

Does my partner also need to be tested or treated?

Don't hesitate to ask other questions during your appointment.

What to expect from your doctor

Your doctor is likely to ask you questions, such as:

Do you notice a strong vaginal odor?

Do your symptoms seem tied to your menstrual cycle? For instance, are symptoms more intense just before or just after your period?
